Agenda and Notes

1. Operations Status and Summary

Operational at 12 GeV and traded trips for repetitive down times.

Will analyze over the next few days.

Beam ops 28th January

Jan 18-28 can RF/cavities operate without beam. Turn on/off infrastructure see microphonic effect.

Daly will compose "He boiling" TP

C100 tests (determine best pressure "defined by highest operating gradient" to operate at)

destinguish/study SEL GDR trip differences (Rama)

2. C75 Project (Freyberger)

Project Internal Review: Thursday January 21 (Morning) Responsibility for Program/Agenda?

Cavities (FM) HOM (FM) Cryomodule (ED) Hygiene Plan (GG) Rimmer/Krafft (Specifications) Prototype Data Summary (FM) RF Power (Hovater)

Committee C Reece (chair), Andrew, Cardman)

Goal: Preliminary design review


3. Particulate-Free UHV Meeting (Geng)

Schedule for February 29 Program? Rong-liu will put together an agenda beginning of next year


  • First Draft version is attached below, modeled on tables in the

Cornell ERL "Project Definition Design Report". It contains input from Rimmer, Hutton, and Krafft but needs work on the cryomodule side. Daly and Mounts to help complete. Arne to derive cooling power requirement for charter document. Arne suggested publishing in tech note in about 6 weeks. Krafft will shepherd.

4. CEBAF Beamline Vacuum (Geng)

Action Items

Complete Project Charter Document; Project Leader (Freyberg, Rimmer, Krafft, Hutton)

Data mining for field emission (Geng)

C75 parameter table! (krafft, rimmer, marhauser)

Heat For Project Charter (freyberger)

Kimber and Nelson to invite list (Krafft)
